OK boys and girls, for those of us who lust after conversions, we may have a problem. Two Richards Type II conversions are in the shop right now. There MINE Dammit. Same problem both guns.
Take your Barrel and Cylinder off and inspect the breach face of the conversion ring, around the hole for the firing pin. On both of my guns, the firing pin was hitting the frame lightly at the bottom of the firing pin hole, but hard enough to spall off a chunk of the color case and leave a crater with sharp edges.
The primer cup flows back into the crater with sharp edges, creates an instant "high primer" and locks the guns up solid. I do mean solid. Cylinder will not turn without a LOT of help.
So far I've relieved the bottom and both sides of the firing pins and and had at the hole with a needle file. Case hardened so the file is now kaput and I'm in the process of filling the craters and facing off the breach face to make everything smooth again.
It looks to me like this may be a common problem with the Type IIs. Incidentally, this happened with light main springs at the first match I fired these guns in. Not real impressed am I.
Everybody needs to look at their Type IIs.
